Description: The Geekcreit UNO R3 is a fully Arduino-compatible board powered by an Atmega328p and CH340G serial interface. While a clone to the Arduino UNO R3, it functions exactly the same and is fully compatible with the Arduino Software (IDE). Clone UNO's can be manufactured under the creative commons files provided on the Arduino website.This is a bare board kit, if you have a spare USB A-to-B cable and some headers or a shield you are good to go, save money and the environment by not adding another cable to that pile you already have. Features: All the cool details Fully compatible Arduino UNO R3 clone board High build quality Great for Education, Hobbists and Projects Quick start guide: Do not connect the UNO board until you have followed these steps. Download the latest Arduino IDE Download the CH341 USB x86/x64 driver Plug in UNO development board, the driver will be installed automatically Start the IDE and select the UNO R3 as your target Select the COM port, you may need to check device manager if unsure of this.

Description: A4988 is a complete microstepping motor driver with built-in translator for easy operation. This product is available in full, half, 1/4, 1/8 and 1/16 step modes operate bipolar stepper motors, output drive capacity of up to 35 V and ± 2 A. A4988 includes a fixed off-time current regulator, the regulator in slow or mixed decay modes. A4988 converter is the key to the easy implementation. As long as the "step" input inputting one pulse drives the motor one microstep. There are no phase sequence tables, high frequency control lines, or complex interfaces to program. A4988 interface is very suitable for complex microprocessor is unavailable or is overburdened. In the micro-step operation, A4988 chopping control inside automatically selects the current decay mode (Slow or Mixed). In mixed decay mode, the device is initially set to a fixed downtime in some fast decay, then the rest of the slow decay downtime. Mixed decay current control scheme results in reduced audible motor noise, increased step accuracy, and reduced power consumption. Internal synchronous rectification control circuitry is provided to improve the pulse-width modulation (PWM) operation power consumption. Internal circuit protection includes: thermal shutdown with hysteresis, undervoltage lockout (UVLO), and crossover-current protection. Special power sequencing. A4988 surface mount QFN package (ES), a size of 5 mm × 5 mm, nominal overall package height of 0.90 mm, with an exposed pad for enhanced thermal dissipation. This package is Pb (suffix-T), with 100% matte tin leadframe plating. Feature: Simple step and direction control interface Short-to-ground and shorted-load protection Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay) Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor’s rated voltage to achieve higher step rates Package included: 1 x Step motor driver module 1 x Heatsink
Description: Telsa coils are cool, who cannot resist playing with mini lightning ⚡? This Geekcreit Mini Tesla Kit is a great educational toy, it works much as you would expect producing mini sparks of energy you can interact with, it also has an audio input allowing you to produce sound based on the audio input. The kit is unassembled and you'll need to provide a power supply to drive it, most laptop power supplies with a barrel jack will be fine for this. You'll need basic soldering skills to assemble the kit.A Tesla coil is a transformer that operates on the resonance principle. It was invented by Nicola Tesla, a Serbia American scientist in 1891. It is mainly used to produce ultra high voltage, but low current, high-frequency AC power. The Tesla coil is composed of two groups of resonant circuits (sometimes three groups) coupled. Nicola Tesla tried a large number of configurations of various coils for his experiments over the years, such as electrical lighting, fluorescence spectrum, X ray, high frequency alternating current phenomenon, electrotherapy, and radio energy transmission (such as Wardenclyffe Tower), among others. Features: All the cool details Great educational product Unassembled kit, requires basic soldering skills to assemble Requires DC power supply, a spare laptop supply with a barrel jack will do the trick Tesla coil functions: Electric arc function: the traverse of the rear end will produce an arc. The arc can also ignite Power transmission function: after the Tesla coil is charged, small LED's and bulbs can be wirelessly powered Music playback function: a new concept loudspeaker for an electric arc to stimulate air to make air vibration produced by plasma. You can play mobile/computer music, but the sound is small. Assembly tips: 1. Install small components at first; 2. Install complex components preferentially; 3. Pay attention to the installation direction of components. 4. Make sure the soldering iron does not touch the components for a long time. Otherwise it is easy to damage the components. Safety notes: 1. This product is safe, power is not high, will not be injured by electric shock, but it is not recommended to touch the top of the coil arc, there will be a sense of burning. 2. Do not touch the heat sink after a long time power supply, the temperature is very high, especially the use of 24v high voltage heat huge, if necessary, add their own cooling fan cooling, or working hours lead to too hot, please turn off for a period of time Electric use. 3. Tesla coil is recommended to work when the body or other objects close to the coil, the coil next to half a meter blank can not be other objects, as other objects as a good conductor will make the coil form a good loop, absorbing the coil energy, making Testers Pull the coil at this time the effect of demonstration or deterioration can not be demonstrated! 4. Do not put cell phones, mp3 and other electronic equipment close to the coil, or the coil will produce high-frequency magnetic field interference, making mobile phones, mp3, and other equipment failure or damage!
